EDGAR TREGONING, OF ATTLEBORO, MASSACHUSETTS.

- seamen.

To all whom it may concern:

Be it known that I, EDGAR TREGoNInG, of Attleboro, county of Bristol, and State of Massachusetts, have invented certain new and useful'lmprovements in Rosettes; and

I do hereby declare the following specification, taken in connection with the accompanying drawings, forming a part of the same, to be a full, clear, and exact description thereof.

My invention relates to electrical rosettes and similar electrical fittings which are adapted to support electric lamps and similar devices and in which conducting wires are connected to suitable terminals or bindknot which is located in a recess with-in'the rosette so that any strain on the conducting wires will come on the knot instead of on the terminals. This practice of forminga knot in the conducting-wires, however, is objectionable because the forming of the knot is liable to break the insulation, and

- the knot is also liable to pull through the central opening in the rosette.

It is the ob ect of my invention to provide a novel form of rosette in which a very simple and efiicient means for relieving the strain upon the terminals is employed. To this end my invention consists in the novel form of rosette hereinafter described and claimed, reference being had to the accompanying drawings, in which-- Figure 1 is a side elevation of my novel form of rosette,'Fig. 2 is a top plan view of the same, Fig. 3 is a top plan view of the base of the rosette, Fig.4 is a bottom plan view of the cap or cover, Fig. 5 is a vertical section on the line a2-a:, Fig. 2.

Referring to the drawings, Fig. 1 shows a usual and well-known form of rosette in which the body portion is made in two parts and comprises a base portion 1, supporting the usual main wire terminal plates 2, and a removable cap portion 3 having a central opening 4'through which extends the lamp- Specification of Letters Patent.

cord 5 comprising the two wires 6, as shown in Figs. 4 and 5.

Mounted by screws 7 in opposite sides of the cap 3 are spring-plates 8 which are constructed and adapted to engage the springplates 9 formed upon the inner ends of the terminal plates 2, to lock the cap 3 upon the base 1 and to forman electrical connection between said cap and base. Mounted by screws 10 in opposite sides of the cap 3 are plates 11 provided with wire terminals or binding posts 12 and fuse terminals 13. The bases of the spring-plates 8 are provided with extensions in which are mounted fuse terminals 14, and extending between the fuse terminals 13 and 14.- in a groove 15 formed in the body portion of the cap 3 are fusewires 16, all as shown in Fig. 4.

Formed integral with the body portion of the cap 3 are two upright vertical studs 17 located upon opposite sides of the central opening 4 and adjacentthe wire terminals 12. The ends of the wires 6 are coiled around the studs 17 and secured to the wire terminals 12, andthe free ends of the studs Hare arranged to overlie a central boss 18 formed upon the base 1, so that the said wires 6 will be held in place upon the studs 17 when the cap 3 is in position upon the base.

' With the above construction the rosette can be quickly wired up, and all the strain of the cord 5 and wires 6 will be upon the.

studs-17 and the terminals 12 are entirely relieved from all strain. As will be seen, the length ofthe studs 17 may be varied to accommodate any desired number of turns of the wires 6 by simply varying the depth of the cap3.

While I have described my invention as applied to a two-piece rosette havin a base and a removable cap, it will be un erstood that it is also adapted for use in a one-piece rosette in which the base and cap are integral.

What I claim as my invention and desire to secure by Letters Patent is: r

1. An article of the character described comprising a base provided with an inwardly extending boss, a removable cap provided with a central opening, two wire terminals, and two strain receiving members arranged to overlie the boss formed upon said base.

2. In an article of the character described,-

the combination with a base providedwitlr a central boss, of a removable cap provlded body portion upon the interlor thereof and located adjacent said wire terminals.

4. In an article of the character described,

. the combination, with a body portion provided with a central opening, two wire ter minals and two vertical studs, of an electric lamp-cord extending through said central opening, and having its inner end portion coiled around said studs and connected to said wire-terminals.

In an article of the character described, the combination, with a body portion provided with a central opening, two wire terminals and two vertical studs, of an electric lamp-cord extending through said central opening and having its inner end portion coiled around said studs and connected to said wire terminals, and means for hold ing the coils in position upon said studs.

6. In, an article of the character described, the combination, with a body portion.comprising a base and 'a removable cap portion,

each provided with a pair of Wire terminals,

and means for connecting the wire terminals upon the base portion with the wire terminals upon the cap portion when said ca portion is secured to the base, of a centra opening in said cap portion, two vertical studs formed upon said. cap portion and an electric lamp-cord extending through said central opening and having its inner end portion coiled around said studs and connected to said wire terminals.

7. In an article of the character described, the combination, with a-base portion provided with two wire terminals, of a cap portion provided with a central opening, two

wire terminals, an electric lamp-cord extending through said central opening and having its inner end coiled around projection's formed in said cap portion and connected to the wire terminals in said cap portion, and a pair of fuse wires extending from boss, of a removable cap portion provided with a central opening, two wire terminals and two vertical studs formed integral with said cap portion and having their free ends overlying the central boss upon said base portion when the cap is in position thereon,

a lamp-cord extending through said central opening and having its inner end coiled around said vertical studs and connected to the wire terminals in said cap portion, and

a fuse wire extending from each of the wire terminals in said cap portion through suitable grooves to a pair of fuse wire terminals arranged and adapted to engage and disengage the wire terminals upon thebase por- V I EDGAR TREGONING. Witnesses: v 4
